How NG112 Works
A practical walkthrough of the functions that can sit between a caller, the originating network, an Emergency Services IP Network and the answering PSAP.

112 readiness
Policy, location, routing, and response quality connected in one operational model.
The short version
NG112 is not a new public number. It is the technical evolution of emergency communications behind 112: IP networks, SIP emergency sessions, better location handling, data exchange, accessibility and more interoperable PSAP connectivity.
- Citizens still dial 112.
- Originating networks may include mobile, fixed, VoIP, enterprise UC, emergency apps and connected-vehicle systems.
- Emergency routing should be driven by verified location and policy, not assumptions.
- Implementations differ across Europe and must be described from source evidence.
What is NG112?
NG112 is the modernization of Europe's 112 emergency communications environment toward IP-based routing, richer location, data, accessibility and interoperability.
112 vs E112 vs NG112
The difference between the number people dial, enhanced caller location, and IP-based next-generation emergency communications architecture.
